Mark, I have an EyeFi card on the way and just picked up a used ipad2 for a really good deal. From what I can tell, you would need to jailbreak your ipad and install the app MyWi which will give you the ability to set up an AD HOC connection from your iPad directly. Then you can use apps like shuttersnitch to tether without having to include a pc into the mix. Of course, there are ways to set it up so you are tethered directly to your laptop while having the images show up on the iPad as well. I can't wait to experiment myself.

If you end up getting one, keep me posted?
